I hate this sort of crap. Why does this have to be so painful?
He already had a traumatic experience and just when he was starting to recover when he was starting to forgive the violin and to forget his bast**d of a father, Saeki has to go and ruin it.
Can he be just a little more considerate? Honestly, wth? I'm pretty sure he had an idea of what Aono was going through. To literally bring that up out of nowhere during an EXTREMELY sensitive time... Uh, hey, your father had an affair with my mother and so yeah, we're brothers!
You do not just randomly blurt that out.
I do not blame Aono at all. It's an entirely reasonable reaction. Just think about it. If it was you, you'd probably do the same thing. Can anyone blame him for lashing out?
Maybe it's just me, but I'm hoping that Saeki suffers more and it takes longer for Aono to forgive him. And Aono stopping violin for a while and Saeki feeling really guilty and depressed because he literally was the reason for everything. That would be nice.
